Abstract
In order to suppress any reduction in the reception performance of an optical transceiver, the optical transceiver includes a light source, an optical splitter that splits the output of the light source into a first split light and a second split light, an optical modulation unit that modulates the first split light, a coherent receiver that causes the inputted received light to interfere with the second split light, and a first control unit that controls the split ratio of the optical splitter on the basis of the reception characteristic of the received light received by the coherent receiver.

An optical transceiver comprising:
- a light source;
- an optical splitter configured to split output of the light source into first split light and second split light;
- an optical modulator configured to modulate the first split light;
- a coherent receiver configured to cause input reception light to interfere with the second split light;
- a first controller configured to control a splitting ratio of the optical splitter, based on a reception characteristic of the reception light received by the coherent receiver;
- a light intensity monitor configured to monitor power of transmission light of the optical transceiver,
- wherein
- the first controller adjusts the splitting ratio, based on output of the light intensity monitor.
